SEVERIN HALVORSEN, or snArrLnwasi-Irneron, Assrenon no rain nnwsrarnia STUFFING iaacmnnsconzranr, on sna'rrnn, wasnrnsron, a coraroaarron OF WASHINGTON. y

To all :whom it may concern:

Be it known that I, .SEVERIN HALvonsnN,

a citizen of the United States of America,

and resident of Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Newspaper-Stufiing Machines, of which the following is a specification.

My invention relates to apparatus designed for assembling the several sections of a newspaper so that one section constitutes a cover or inclosing section and the other sections are Within the cover section. The process of assembling the parts of a paper is generally referred to as stufling. l have therefore termed my invention a newspaper stufling machine.

The object of my invention is to provide an apparatus which is'capable-of stuffing papers at a high rate of speed and which is reliable and accurate in its work.

The particular features of which my invention consists will be hereinafter set forth and then particularly defined in the claims.

In the accompanying drawings 1 have shown my invention embodied in the forms which are now most preferred by me.

Figure 1' is a side elevation of the machine, the view being from the side containing most of the operating connections and that occupied by the operator.

- Fig. 2 is a top plan view of the complete machine.

Fig. dis a side elevation similar to that of Fig. 1 except that parts of the machine are broken away and much of the working parts at the interior of the machine are shown in dotted lines.

Fig. 4t is a transverse sectional elevation taken on an irregular or oiiset plane indicated approximately by the line 4-4: of Fig. 3.

Fig. 5 is a horizontal section of the central part offthe machine taken on a plane above the paper carrying table, except that the paper supporting fingers at the end. of one set of feed chainsare removed.

Fig. 6 is a horizontal section taken on a plane just below the paper carrying table and its feed chains, showing the central parts of the machine.

Fig. 7 is a'horizontal section taken at a still lower level through the parts which de liver the paper sections to the St fi ng point.

I have herein referred to my device as a newspaper stuiling machine and will so describe it, although it may be used for assembling sections of pamphlets, books, circulars and other similar products. A specific reference to such uses is not deemed necessary in .the description of the mechanism employed and its principles of operation, it being understood that it is intended to employ these mechanisms for any and all purposes for which they are adapted.

In the drawings I have shown mechanism capable of assembling two newspaper sections within a third, that is, a machine capable of stufiing a paper composed of three sections.

A machine of this character and capacityis believed to be capable of handling and stufling the various sections of substantially all editions put out by even the largest papers.

Where such editions are composed of more than three sections, some, or many, of these sections, will be printed in advance, and

these may be stuffed in advance and these stuffed sections then be treated in the same manner as were, the unit sections of which they are composed, to assemble the whole within a cover section. Some of the unit sections may alsobe run collect on the press. If desired, however, it would be an easy matter to add other paper delivering mechanisms, to deliver their sections at the point of assembly, within the cover section. I provide a series of feeding tables or'- racks for the reception of the paper section which are to be assembled, these correspondmg in number with the number of sections to be assembled. Ihave shown three, these being indicated respectively by reference characters A, B and C, for purposes of separate reference. These are each essentially I alike in' their construction and operation and a descriptionof one will suffice for all.

In the drawings I have shown these pa'per receiving and feeding tables as arranged in line, A and B being at the same level and C at a slightly lower level. This arrangement is, to a certain extent, arbitrary. The conthe point of assembly, wouldbe a simple matter. 4

In the machine as herein shown, the paers are arranged in vertical position, the folded edge down and resting upon the feeding table. The position occupied by the papers in the separate piles, is immaterial, except as itmay a ect the operation of the particular mechanism employed by which the individual sections are detached from the pile and delivered to the conveying mechanisms. v

The mechanisms employed in this machine .may be grouped, in accordance with their function, into three groups, as follows.v

ends of the papers to keep them-in place;

Paper feeding means are employed to secure gradual movement of the pile of papers toward the point where they are removed, one at a time, and delivered to the conveying means. 1 I

With the papers vertically disposed, as shown, the conveying means which I have chosen, consists of a series of endless chains 1, which have one run passing over the table 10 toward the paper delivering end. The wheels at one end, as the whe ls 12, may be idlers. The other wheels, as 13, are the drivers.

I prefer that the driving wheels, 13, be yieldingly driven, so that they may advance as fast as the papers are taken away, but no faster. I therefore employ a friction actuated device to,drive the chains: I have also preferred to employ, a separate friction drive for each wheel 13. A preferred construction for this is shown in Figs. l9 and 20.

Shaft 14; has a member secured thereto consisting of a sleeve 16 and a flange or disk 15 at one end. Mounted to freely turn upon on, as by having intermeshing key and keyway. One disk 17 and the flange or disk 15 has a washer 18 of a material making a good friction hearing, as fiber, which engages opposite sides of the wheel 13. Be;

tween disks 17 are springs 19 which act un-.

der compression to grip the'wheel 13 and turn it. A threaded-backing nut.l7, takes the 'thrust of the springs in one direction and may be adjusted to vary the pressure upon the wheel 13,

Each shaft 14 is 'turhed t rough a friction clutch device, a preferred-form being shown inFigs. 23 and 24. This comprises a wheel or disk 25, secured to shaft 1 and having I a series'of inclined surfaces 26 and inclosedv within an encircling bandv or case 28, which is oscillated through a rod 22, which is con-- nected with. an arm 29. Rollers 27 engaging between inclined surfaces 26 and casing 28, permit free movement in one direction, but bind the two together when moved oppositely. To insure against back movement, a reversely acting clutch or ratchet mechanism may be employed, as the ratchet Wheels 24 and pawls 23.

The rods 22 are actuated by engagement with rock arms 21 carried by rock shafts 20. The two rhck shafts 20 are connected by a rod 20*. The rock arms 21 are slotted to permit adjustment of the point of connection of rods 22 to vary its movement. The amount of feed is thus adjusted to the thickness of the. paper, sections being handled. One of the shafts 20 is actuated through an arm 2 and rod 2 from a crank pin 2".

The above mechanisms will deliver the paper sections to the point where the feed ing mechanisms act upon them. The paper feeding mechanisms which I prefer to employ in the type of machine herein illus trated is as follows:

Vertical plates 30 have vertical grooves or guide ways which receive vertically reciprocable feed bars These are actuated through links 31 which connect them with rock arms 32 carried by rock" shaft 20. For easy engagement and disengagement, the ends of rock arms 32 may be slotted and the pins 33 clamped therein by any suitable means.

Upon their lower ends bars 3,v carry paper feeding pins. This mechanism is shown in detail in Figs. 12 and 13. One sideof the rod 3 is recessed to receive a hlock'3 l which is pivoted to swing freely upon securing bolt 39. A spring 37 acts to swing its needle carrying end toward the pile of paper sections. A finger 38 contacting with a shoulder of the recess in the bar 3 limits this movement. A. separate block 35 forms the paper engagingend of this member and has therein a hole for the reception of a needle 36. A series of these needle carrying blocks are secured to each rod 3.

The paper supporting table, at the paper feeding end, terlninatcs in' a series of fiat bars 4, which are adjustable to vary the distance separating their ends from the feed bar 3, therel'iy determining the width of the opening through which the papers are fed. The bars 4 are shown having a longitudinal slot 40 through which the securing screws -11 pass. The plates 42 to which the bars 4: are secured, are secured to the frame by screws or bolts pass ng through transtt versely extending slots at their ends, as

"their upward or retractive stroke, but on the downward stroke, the needles 36 engage the outermost paper section to carry it down until it is engaged by the feed rolls 5 and 52 and the feeding and conveying tapes 50, carried by theserolls. The shafts 51 of these rolls are connected by gears 53 (see Fig. 2), so that they rotate in unison.

Rolls 5 and 52 of each pair are spaced apart to pass a paper section between them and to presslirmly upon it in passing. The

shafts of rolls 52 are journaled in blocks- 54, which may be adjustable in slots 45 of i a member 44 which is fixed to the frame.

Block 54 is adjustable to vary the separ tion of rolls 5 and 52. It has a stem 55 which projects through a part 57 of the frame. The adjustment provided consists of a slot 550 out across the outer end of stem 55 and an adjusting plate 58 which is pivoted at 580, and is secured inadjusted position by a clamping bolt 59, which passes through an arctuate slot 581 in the plate 58. The lower edge 582 of this plate is inclined to act as a cam against the side faces of the slot 550, to thereby move stem 55 when plate 58 is turned upon its pivot bolt. An, index finger 583 may be used with an. index are 570 as a guide for the amount of iuiljustnient. A spring 56 holds the roll yieldingly toward roll 5 and takes up whatever slack there may be in the positive adjusting means employed.

The plate or bar 42, carrirs a series of mechanisms which are designed to prevent the feeding of more than one paper section at a time. The preferred construction of these is shown in detail in Figs. 12, 13 and let, and is as follows:

A block 6 is recessed in. a socket formed in the edge of plate 42, beneath each of the bars 4-. .A stem 60 fixed to this block forms a seeming bolt. Needle lever (37 is pivoted at 68, back of a protecting plate 69 which between rollers (i l and the opposed fixed plate G l", without forcing back the rollers. Under such conditions the i'iecdles 65 are not projected. If however, two paper sections should start together, as has been shown at the right hand in Fig. 12, the added thickness will force back the rollers 64, thus pro jectmg the pins 65 and catching and re-' taining the. second paper until its turn comes.

" be needed.

The stack of papers at A are those destined to form the cover or news section of the stuffed paper. The papers of the stacks at B. and C may be respectively the color and the classified sections, or may each be composed of two or'more sections which have been previously stuffed.

' By reason of'opera-ting the paper feed bars 3 for sections A and B, from opposite ends of the same oscillating levers 32, these sections are started alternately. In the position'shown in Fig. 9, the bars 3 are at the middle of their stroke, the direction of their movement being indicated by the arrows carried by each. The cover or news section which has just been started out is shown at D, between tapes 50, its lower edge not yet having reached the lower tape rollers 78. The shafts 7, 7 which carry the tape rollers 78, also carry the cover-opening rollers 70, 70', which are shown in detail in Figs. 16, 17 and 18. These opening rollers are alternated on'the shafts with the tape carrying rollers 78, as is indicated in Figs. 4, 6 and 7. Tape rollers 78 are not secured to shafts 7 and 7, but are free to turn thereon.

These openingrollers should be of such constructionas will promptly and securely grip the papersand control them without slippage, as their proper functioning depends upon this. To secure this result I have provided'themwith needles which posi- H tivelyengage the paper.

The main body of these rollers is fixed to the shaft and is cupped out or hollowed at one end, making a cavity which is interiorly threaded to receive a needle proj ecting cone 77. A series of needles'72 have I their heads engaged by the coned surface,

whereby their projection may be adjusted by adjustment of the cone 77.

Springs 76 acting against the heads of the needles, withdraw them as permitted by backward movement of cone 77. The section 74 is a band nut screwing upon the reduced collar 7 4. Between this band nut and the projecting needles is interposed a ring 73'of copper or like relatively soft metal into which the needles may be made to sink slightly on tightening the needle-clamping band-nut 74. The tape carrying rollers 78 run loose on the shafts 7, 7.

The shafts 7, 7 are connected by gears and 7 of which the latter'is the smaller, sh -that shift 7 turns the faster.

gear 7 which meshes with gear 7 on the main drive shaft E. v

The tapes 50 which bring down. the paper sections from the stack B, at their lower ends pass over idlers 50 of which the one 'farthest removed from the opening needlerolls 70, 70, is located slightly lower and under the other, thus making adjustment for'differing thicknesses of paper sections unnecessary, and also giving the paper a lateral de-.

flection toward and into the opened cover' section. The shafts carrying the idlers 500 for the tapes bringin the third paper section from the stack are made relatively adjustable by mounting one shaft in blocks 501 which may move in guides 503, springs 502 holding these rollers yieldingly together, and adjusting bolts 504 limiting their approach. These tapes discharge their papers horizontally into the opened cover section.

I provide a series of sto s which are operated to check and time t e various paper sections so that the delivery of the filler sections may be properly timed with the opening of the cover section.

Shaft 7' has a Stops 8, for the cover section, are carried by arms 80 secured to rock shaft 81, to swing into and out of the path of the cover section to momentarily check it just above the opening rolls 70, 70'.

Stops 82are similarly carried by arms 83 secured to rock shaft 84 to control the -delivery of the first filler section. Stop 85 carried by rock shaft 86 controls the time of delivery of the second filler section. Rock shafts 84 and 86 are connected through rock arms 87 and link 88. A stop 821, carried by-i-ock shaft 820 engages the cover section to hold it in position for receiving the filler sections. The stop-carrying arms 80, 83, 85 and 821, may be adjusted by loosening set bolts 89;. r

Rock shaft 81 is actuated to withdraw stop 8, through arm 810 which carries roller 811, engaging cam 812 mounted on the main shaft E, spring 813 throwing the stop into active position.' See Fig. 9. A bar 8 outside the tape holds tape and paper-back while these stops are being withdrawn.

Rock shaft 820 carries rock arm 822, which is connected by link 823 with rock 827 and cam828 upon main shaft E. Spring 829 acting through rock arm 830, draws the stop into active position. i I

Botk shaft 825 also serves as'a pivot' beartarmac ling tor a rock arm842, which carries cam roller 843, engaging cam 844 secured. upon the main shaft 1). rice l igs'. 3 and 6. Rock arm 842 is connected by link 841 with rock 5 arm 840, secured' to rock shaft 84. Spring 845 retracts these parts, holds cam roller 843 against its cam, and throws stops 82 and 85 into active position.

Paper supporting and guide fingers 9, receive the papers while being stufl'ed. These extend from beyond the stops 821 upwardly at an angle, approximately as shown, to the delivery ends of tapes156. Supplemental tapes 500, passing over pulleys mounted upon shafts 500 and 92, are also used, Fingers 9 have raised portions 90 and 91 which. hold the upper edges of the paper clear of the tapes 506, but are depressed so. as to cause the paper to contact with the tapes below the ledge 90.

Tapes 97, 98, passing over rolls 493 and 49, convey the stufied papers away. Tapes 48 connect rollers on shaft 7 with rollers on shaft 490.3.v The latter assist in the opening of the covdr section in a 'hiannerwhich will be later explained; j

,A rock shaft; 200 carries rock arms 201 which are slotted at their outer and embrace pins 208* carried by paper holding.

an fingcrs 204 whichireciprocate in guides 205, The lower ends 206: of these fin ers extend" beneath the discharge opening between the paper opening rolls 70 and/Z0. A bar 207,

positioned. to be engaged by the lower ends (if these fingers, cotiperates to hold between them the upper edge ,ef one side of the opened cover section, as is shown in Fig/11. Shaft 200 carries a rock arm 202, and this a roller 208 which is in position to engage the sectionalcam flange- 209, to thereby give the fingers 204 a reciprocating movement to raise them, as is shown in Fig; 9, or depress them, as in Fig. 11. In Fig. 10 both positions are shown, one being in broken lines. Sprmg 210 acts upon an arm carried by shaft 200, to hold the roller in contactwith its cam and to normally hold the fingers 204 raised. A. stop 211 limits the movement given by the spring.

.50 The tapes 48, 97, 98 and 506, are all turned by a chain 93 which engages wheels 94, 95,

96 and 92? to turn them, the wheel 95 being an idler. 'Eiee Figs. 3 and 6.- Shaft940 carri-es wheelsa94 and941, the latter engaging wheel 942 carried by the main shaft.

vertically moved within guides 903 and is supported by pivotal connection at 904 from lever 905 which is pivoted at 909. Adjustingbolt 915 limits downward movement and therefore controls the minimum approach of rollers 913, 914 to, rollers 900 and 901. Spring 906 assists prompt drop of rollers 913, 914 after their having been raised.

A link 907, of adjustable length, connects lever 904 with a switch 910, pivoted at 911.

position shown in Fig. 25, in which the papers would be shunted downward, beneath conveyor 912. With rollers 913 and 914 raised, the switch pointwould be depressed and the papers would pass out upon the conveyor 912. A fixed table or plate 908 lies just within the lower delivery tapes 97 underdetector rollers 913 and 914.

This device is set to provide a separation between rollers 900, 901 and rollers 9.13, 914, to .correspond with the thickness ofa properly stuli'ed paper. Such a paper entering between these rollers, will raise the upper veyer 912. Shouldz'the paper be lacking some of its sections, itwill' be'thinner andwill not raise roller 913, 914 and the switch oint, will be retained in raised position and The operationof the machine is as follows:

The var ous 'sections which, assembled,

form the complete paper, are placed in their proper places, as has been indicated by the stacks A, B, C,'the cover section being placed at A, The reciprocating needle bars will each discharge a section at a time between the"tapes.

As-the cover section reaches a point approximately indicated as 300 in Fig. 11, a sectionfrom stack B is stanted through its l'ifitllgfi f g l llflr cover section is momentarily checked, if this is necessary,--by stop 8. This position is shown in Fig. 9, wherein the sec- 0nd section is just entering between its tapes. When the cover section is released from stop 8, it passes between the paper opening or needle rolls 70, 70. The roll 7 0 running faster than the roll 7 O, feeds its half 302 of the paper faster than roll 70 feeds its half 301, producing the ballooning elfect shown by the full line position of Fig. 10.. In this position the half 302 is about to be discharged by the roll 7 0. In this position the half 302 of the paper contacts with the tapes 506, which tends to throw and hold the fold against the opposite tapes 48, these gently drawing the fold down toward the apex of the chamber formed between tapes 48 and 506.

v The momentum given the half 302 by the needle roll 70', at the moment of release supplemented by the frictional action of the I tapes 506, throws the half 302 down upon the ides 9, as soon as it is released from the needle roll 70. This position is shown by the dot-and-dash line of Fig. 10, and by the full lines of Fig. 11.

Just prior to the cover section reaching this position, the fingers 204 are thrown down, catching the upper ed e of the half section 301 between them an the bar 207, detaining this half of the section'and holding the section opened for the reception of the filler sections. The upper or free margins of the cover section rest upon the ledges 90 with its edge under the 1edge'91, so that the incoming filler section delivered through the tapes 156 cannot get under it.

The filler sections 303 and 304, when releasedby removal of the stops 82, 85, are shot out from between their tapes into the opened cover section, these being shown in Fig. 11 as emerging from their conveying tapes. As soonas these filler sections have been fairly entered within the cover section, the fingers 204 may be withdrawn, releasing the upper half of this section and permitting it to fall, as has been shown in Fig.'

9. At the time the filler sections are in their final position, or possibly a mere instant in advance'of this, the stop 821 is removed and the stuffed paper discharged between tapes 97, 98. By releasing stops 821 just in advance of final seating of the filler sections, the momentum of the latter may be utilized to start the stuffed paper through the delivery'tapes.

The release of the upper halfof the cover section by the fingers 204, may occur at any time after the filler sections have entered the cover section and before they have become seated therein. such condition isfshown in Fi 9.

It will be noted that the tapes 48'and 506 chamber of triangular shape, converging'at the discharge end where it communicates with conveying tapes 97, 98, and that th( axis of this chamber, that is the line which bisects'the angle between its sides, extends across the line of discharge of the cover section. The position and general arrangement of these parts each contribute its part in the successful operation of the device.

The movement of tapes 506 in a direction transversely of the path of movement of the cover section by engagement with the side of the cover section'which is lowermost during the stufling operation, combines with the throwing actionof the needles of roll to quickly throw the lower half of the cover section down flat. The position of the paper at this time is such as insures correct insertion of the filler sections.

The paper opening means composed of the needle rolls 70 and 7 0, may be set to open a stuffed section, that is, one which is composed of two or more sections, and to open it at any point desired. If it is desired to open it at the center, the needles should be projected enough to pass through the outer of the innermost section, or to cause the needlesof each roll to engage the section of paper lying at its side of the place where the paper is to be opened. This point of opening such a section need not be at the center, but'may be made at either side of the center, this being secured by causing the needles of one roll to project-more than the needles of the other. The needles of the two rolls should not overlap. The use of this opening mechanism is notlimited to newspapers alone but may be applied to books, pamphlets, circulars, etc.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States of America, 1s:-

1. In a paper stufling machine, a mechanism for opening a folded paperv having two uniformly moving paper feeding members engaging opposite sides of a folded paper and operating at rates of feed which are different for the respective sides.

2. A mechanism for opening a folded paper having two paper feeding members between which the folded paper passes,

means for actuating said members in like direction but at rates of feed which are constant but differ as between the sides.

3. A mechanism for opening a folded paper having two feed rolls turning at constant.

- but different rates between which the folded paper is passed.

4. A mechanism for opening folded papers having two needle rollers turning at constant but different peripheral speeds between which the folded paper is passed.
